Aleast squares regression line was found. using technology, it was determined that the total sum of squares was 278.0 and the sum of squares if regression was 274.3. use these values to calculate the coefficient of determination.

4. (10.03 mc) the equation of line cd is y = −2x − 2. write an equation of a line parallel to line cd in slope-intercept form that contains point (4, 5). (4 points) y = −2x + 13 y = negative 1 over 2 x + 7 y = negative 1 over 2 x + 3 − 2x − 3
